Abstract: Compositions, methods, and apparatus for manufacturing sheets having a highly inorganically filled matrix prepared by mixing together an organic polymer binder, water, one or more inorganic aggregate materials, fibers, and optional admixtures in the correct proportions in order to form a sheet which has the desired performance criteria. The inorganically filled mixtures are formed into sheets by first extruding the mixtures (40) and then passing the extruded materials between a set of rollers (50). The rolled sheets are dried in an accelerated manner to form a substantially hardened sheet, such as by heated rollers and/or a drying chamber. The inorganically filled sheets may have properties substantially similar to sheets presently made form traditional materials like paper, paperboard, polystyrene, plastic or metal. Such sheets can be rolled, pressed, scored, perforated, folded, and glued.  They have particular utility in the mass production of articles, such as food and beverage containers, and packaging materials.

Abstract: An insulation displacement contact for communication and data transmission has two separated contact legs connected at one end thereof to define a contact slot therebetween, and is fittable into an existing groove extending obliquely across a channel of a housing for receiving wire extending in the channel. The contact allows proper contact with wire having a rigidity lower than 0.4 mm diameter copper wire, and fits within the groove without compromising its rigidity. This is achieved by having a contact portion of each of the contact legs angled in the area of the contact slot such that the contact portions extend outwardly in opposite directions. The contact portions may be bent to the outward positions, may be displaced parallel to each other, and may have cutout sections positioned diagonally-opposite to each other on the contact slot.

Title: Field elimination apparatus for a video compression/decompression system
Inventor: CASAVANT SCOTT DAVID
IPC: H04N19/00
Filed: 1994-01-10
Granted: 2003-08-05
Abstract: Video signal compression apparatus includes a memory (12, 14) for storing two fields of image data and providing fields of image data separated by one frame intervals. Image data from corresponding fields of successive frames are subtracted (16) to generate field differences. The field differences are accumulated (18) over respective field intervals, and the sum is compared (20) against a predetermined value. If a sum of differences over a field is less than the predetermined value, the most recent field is considered to be redundant and may be excised. After respective fields are excised (21), frames of video signal are composed (25) from the remaining fields. The field types (e.g., odd or even) of the fields in the memory are determined (11), and the data is accessed from the respective fields in memory such that data from odd and even fields occupy odd and even lines in the composed frames respectively. Flags (DF, DT) are associated with composed frames to indicate which fields contain data associated with excised fields, and which field of the composed frames should be displayed first.

Abstract: A metal detector has three magnet/coil units positioned end-to-end.  Each magnet/coil unit has a generally rectangular bobbin supporting a coil and a pair of bar magnets at opposite ends thereof.  The three coils are connected electrically in a three-phase "Y" configuration.  The voltages generated by all three coils are received by a microprocessor-based signal processing unit (SPU).  The SPU generates a three difference signals V(x-y), V(y-z) and V(z-x) which represent the differences between the individual coil voltages.  The SPU generates a sum signal representing a sum of the absolute values of all the difference signals and generates a trip signal if the sum signal is greater than a threshold.  The SPU determines over which side of the coil assembly the piece of metal passes by comparing to a threshold the difference signal corresponding to a difference between the voltages from the coils at opposite ends of the coil assembly. The SPU more precisely determines the position of the piece of metal by comparing the difference signals to each other.

Abstract: A unit dosage form of capsule or tablet composed of a large number of pellets made up of two or more populations of pellets/particles.  Each pellet containing a core containing the therapeutic drug and water soluble osmotic agent, which enclose a water-insoluble polymer.  The film coating of each population of pellets differs from the coating of every other population of pellets in a dosage form in the rate at which water passes through to the core and the rate at which drug diffuses out of the core.  The osmotic agent dissolves in the water causing the pellet to swell and regulating the rate of diffusion of drug into the environment of use.  As each population of pellets releases its drugs into the environment sequentially, the effect is to provide a series of pulsatile administrations of the drug from a single dosage form.

Abstract: The present application discloses retrovirus-derived vectors in which the retroviral envelope glycoprotein has been replaced by the G glycoprotein of vesicular stomatitis virus, and the use of these vectors in the transfer of exogenous genes into the cells of a wide variety of non-mammalian organisms. Also disclosed is a method for the generation of retroviral vectors in high titers, wherein a recombinant, stable host cell line is provided which harbors the retroviral vector of interest without envelope protein. High-titer retroviral vector production is initiated by introducing nucleic acid encoding a functional membrane-associated protein into the cell line. The vectors disclosed in the present application can be concentrated by ultracentrifugation to titers greater than 10 9 cfu/ml which are especially useful in human gene therapy trials, and can also infect cells, such as hamster and fish cells, that are ordinarily resistant to infection with vectors containing the retroviral envelope protein.

Filed: 1998-06-25
Granted: 2002-09-03
Abstract: A method and mechanism for aligning a fixed scroll member relative to a main bearing member in a scroll compressor. A shoulder is machined on the outer perimeter of a main bearing member and interfits with an arcuate lip on the fixed scroll member to thereby center the fixed scroll member. A notch is machined into the arcuate lip of the fixed scroll member and receives a projecting pin disposed on the main bearing member when the fixed scroll is assembled to the main bearing member. Relative rotation of the fixed scroll member and main bearing member brings one edge of the projecting pin into engagement with an abutment surface defining one end of the notch and thereby properly rotationally positioning the fixed scroll member. The fixed scroll member is subsequently axially secured to the main bearing member with a plurality of bolts.

Title: Method and device for driving a turn-off thyristor
Inventor: GRUNING HORST
IPC: H02M1/06
Filed: 1998-07-21
Granted: 2005-10-11
Abstract: A method for turning a GTO on and off and a corresponding driving circuit are specified. The turn-on current and the holding current are generated from voltage pulses which are converted into currents with the aid of an electric energy store. In terms of circuitry, it is particularly advantageous when the required voltage pulses are drawn from the same energy source, or the same energy store, as the pulse required to generate the turn-off current. The holding current is preferably generated by repeating voltage pulses.      The repetition frequency of said voltage pulses can then be increased or reduced as required. The frequency is reduced, in particular, when the gate-cathode voltage becomes negative, and is increased again when the voltage is positive again.
